Abstract

The invention provides an implementation method for a control of a slider, which comprises the following steps: a) creating and loading the control of the slider into a parent window; b) calculating the relative position of a sliding block in the slider according to operation information received by the parent window of the slider; and c) setting the relative value of the position of the sliding block into the control of the slider, calculating the coordinate of a starting point of the sliding block according to the set position value of the sliding block, and re-drawing the control of the slider. In the implementation method, when a user implements interactive operation, the control of the slider can send a message to the parent window, the relative position value of the sliding block is modified, and then the control of the slider re-draws the whole slider according to the position value of the sliding block after modification till the display of the relative position of the current record in the whole records. By adopting the implementation method, the user can conveniently and intuitively see the position of the record of the current operation, judge whether the records occur in front and behind the position, and conveniently determine whether a corresponding key can be moved continuously or not for checking the related record. The interface of the control of the slider is simple, attractive and elegant.

Description

technical field

[0001] The invention relates to the technical field of communications, in particular to a method for realizing a slide bar control. Background technique

[0002] Slider controls are one of the most commonly used controls in PCs. Generally speaking, it is composed of a slider, a slider and an optional scale, and the user can display the corresponding value in the corresponding control by moving the slider. Usually, there must be a label control or an edit box control near the slide control to display the corresponding value. Slide controls are widely used in applications, as can be seen in the properties of the desktop. But it's rare on embedded GUIs.

[0003] The existing, based on the embedded GUI graphics library that supports FrameBuffer, because the embedded GUI graphics library that supports FrameBuffer directly operates on Framebuffer, there are no basic graphics controls such as windows, labels, edit boxes, buttons, etc., the programming efficiency ...
